Speed Generating vs Speed Control - RIDE NUMBER EXPLAINED
A TOOL TO HELP YOU SURF BETTER
Using Ride Number is easy, you just have to understand the feelings of Speed Generating and Speed Control. On one end of the Ride Number scale is Speed Generating fins. These fins feel responsive and provide that extra spring most often wanted when the surf is lacking power. On the opposite side is Speed Control. These fins feel solid, engaged, and predictable providing that extra hold usually only needed when the surf is cranking. The middle ground is Balanced, offering a mix of the two extremes for an all around feel. Just remember, When you’re pumping – Speed Generating, when the waves are pumping – Speed Control.
